Two proteins-Tenascin C (TNC) and Apolipoprotein A1V (Apo-AIV), one metabolite-1-Methyladenosine (1-MA) and one phospholipid molecular species phosphatidic acid (PA) showed fairly high cumulative prediction effectiveness for the biochemical relapse of PCa, which had been confirmed in the validation set. The gene discussed is APOA4; the disease is posterior cortical atrophy.
